Hi, I just wanted to get your advice on an older macbook: Core 2 Duo 1.83ghz/2gb/80gb/Combo Drive for $450. Is this a decent deal? I was thinking of getting a netbook, but would this be better? Since I got my mini, I haven't used my MBP much at all, so I was thinking that i would only need something simple as a laptop. What do you think? Thanks!
